Rhizoctonia stem and root rot
scouted Sept. 7, 2021
- Scientific Name
- Rhizoctonia sp.
- Background
- Soybeans in Craven county, variety Moysoy 5607, were scouted and observed with 5% of the field being affected by canker and dieback localized in patches as well as poor nodulation. The site was in a high, sunny, and dry area.
- Conclusion
- The issue was identified as Rhizoctonia stem rot and Rhizoctonia root rot. Rhizoctonia stem rot can result in both pre- and post-emergence damping-off, leading to delayed emergence and stunting of infected seedlings. Rhizoctonia prefer warm and moist soil conditions. Rhizoctonia root rot can result in both pre- and post-emergence damping-off, leading to delayed emergence and stunting of infected seedlings. Prevalence tends to increase in warm and moist, but not saturated soils.
